Most of the processes that shape the landscapes on which we live result from the complex interactions between the topography of the landscape, and the dynamics of fluid (water, air, ice) and sediment transport. Although complex models that mimic landscape evolution are now available, much remains to be done to understand the basic mechanisms an boundary conditions under which the motion of fluids, sediments and solutes shape the Earth's surface. This session welcomes experimental, theoretical and numerical contributions, that address the transport of fluid and sediments over a landscape. This includes, for instance, surface flow mechanics, particle and bedform dynamics, or scale integration.
